On one of my final runs for the day I usually just do a quick spin through the burnout box, no big smoke show just a quick “peel out”. I got on it, to spin the tires up and the wheels when half a rotation and stopped. I thought it popped out of gear, looked down, reshifted, gave it some gas to get upto the lights and all I heard was metal noises. Initially I thought it was clutch, then we checked the “metal” noises which were clearly coming from the rear. All signs pointed towards the ring and pinion 
So we decided to just pull the transaxle out and put my old open diff back in so I could participate in the UBRF track day tomorrow. We put that in, bolt everything up, and i get it in gear to roll it off the trailer and go for a test drive. I let the clutch out, no movement, no shudder nothing. Spano was helping me with the swap gets under the car and the axle is freewheeling as I hear a metal grind and a clunk.
:banghead:
So at this point I’ve atleast ruled out the built transaxle with the quaife and the 2500 mile old Spec 3+ clutch and pressure plate. So I’m really happy thinking “just an axle”. So we pull that one off and I prep everything to go back in as we decide to put the LSD box back in. Spano gets an axle for me off my other car and we’re setup to go. I go about bolting the axle upto the rear hub (passengers side) and when I go to torque it down the entire hub freewheels in my hands with the wheels on the ground…
At this point I’m thinking :banghead:
I’m not 100% sure what is wrong, I assume it’s “possible” to shatter a hub, though I’ve never really heard of it happening on 951’s. Jake originally suggested this. If anyone has any suggestions about the failure, I’m more than willing to hear them. I’m at a bit of a loss here and will be at the track with my BMW all day tomorrow so I wont be working on the car. Oh and for those of you interested, on 17psi I cut a 13.0 @ 117mph, but i shut it down at the 1000’ mark due to a quick fueling issues that spiked up. ET, eh whatever, but the trap is nice for having shut it down
